Strengthening the link between the real and the digital world1ED3121MU12H
5.5 A, 5.7 kV (rms) single-channel isolated gate driver with separate output, UL 1577 certified, 10.5 V UVLO
EiceDRIVER™ Compact single-channel isolated gate driver with 5.5 A typical sinking and sourcing peak output current in DSO-8 wide-body package with large creepage distance (>8 mm) for IGBTs, MOSFETs and SiC MOSFETs.
1ED3121MU12H belongs to the EiceDRIVER™ Compact 1ED31xx family (X3 compact family). 1ED3121 offers separate sink and source output, accurate and stable timing, active shutdown to ensure a safe IGBT off-state in case the output chip is not connected to the power, short-circuit clamping to limit the gate voltage during short circuit. The driver can operate over a wide supply voltage range, either unipolar or bipolar.

Silicon Carbide MOSFETs bring a lot of opportunities to power electronics. However, how to achieve sufficient system benefits by using Silicon Carbide MOSFETs with suitable gate drivers? This training helps you to learn how to calculate a reference gate resistance value for your Silicon Carbide MOSFET; how to identify suitable gate driving ICs based on peak current and power dissipation requirements; and how to fine-tune the gate resistance value in laboratory environment based on worst case conditions.
